Direct coating of mesoporous titania on CTAB-capped gold nanorods.
We demonstrate a CTAB-templated approach towards direct coating of mesoporous titania on gold nanorods in aqueous solutions. The formation of the mesoporous shell is found to be closely correlated with CTAB concentration and the amount of the titania precursor. This approach can be readily extended to form mesoporous titania shells on other CTAB-capped nanoparticles.
متن کاملBSA modification to reduce CTAB induced nonspecificity and cytotoxicity of aptamer-conjugated gold nanorods.
Aptamer-conjugated gold nanorods (AuNRs) are excellent candidates for targeted hyperthermia therapy of cancer cells. However, in high concentrations of AuNRs, aptamer conjugation alone fails to result in highly cell-specific AuNRs due to the presence of positively charged cetyltrimethylammonium bromide (CTAB) as a templating surfactant. Besides causing nonspecific electrostatic interactions wit...
متن کاملCTAB-coated gold nanorods elicit allergic response through degranulation and cell death in human basophils.
The effect of CTAB (cetyltrimethylammonium bromide)- or PEG (polyethylene glycol)-coated gold-nanorods (Au-NRs) on the non-IgE mediated allergic response was studied. We found that the CTAB-Au-NRs released more allergic mediators such as histamine and β-hexosaminidase from human basophil KU812, a common model for studying allergy, after 20 min incubation. Also, the CTAB-Au-NRs induced more apop...
متن کاملMetallographic Observation to Determine a Low-content Gold Alloy Castability
Low gold-content dental alloys nowadays represent viable alternatives to high nobility alloys. The casting techniques and equipment used for low-gold content alloys are similar to those used for conventional gold alloys. This, coupled with their acceptable properties, good clinical performance and lower cost, has lead to their widespread use. The alloy performance in the dental laboratory is an...
متن کاملEnhanced sputtering yields from single-ion impacts on gold nanorods.
Sputtering yields, enhanced by more than an order of magnitude, have been observed for 80 keV Xe ion irradiation of monocrystalline Au nanorods. Yields are in the range 100-1900 atoms/ion compared with values for a flat surface of ≈50. This enhancement results in part from the proximity of collision cascades and ensuing thermal spikes to the nanorod surfaces. Molecular dynamic modeling reveals...
